Multi Language Intergration:integrating system verilog over e

Hi all,

  i have to integrate sv wrapper over e...

  if we integrate by using tlm_nonblocking_put we are facing below error please any body have an idea to resolve this error... 

*** Error: Unsupported template parameter of external interface port
The port 'uvm_test_top.sample_test.env.send_request_p' of interface
'tlm_nonblocking_put of any_sequence_item' has unsupported template parameter
'any_sequence_item'
Struct must contain at least one field which is configured to pass across
multi-language TLM transactions.

Thanks,
